I had been having a terrible high pitched whine coming from my generator and my lights had been dimming for about 2 months, took it to my dealer several times and they said it was fine no problems, they actually told me to just ride it and if it lets go then warranty would fix it. Well lucky for me I met this guy while riding a couple of weeks ago and it turns out he works in the warranty dept at Kawasaki Canada, I told him of my problem and he heard the whine himself and right away told me they had some issues with the stator in the 04, I mentioned to him what the dealer had told me and he was not happy at all. He told me to take it in again and see what they say and if I had any problems to contact him immediately while the bike was still at the dealer, well I took it to the dealer and it was the same response as before so I contacted the warranty guy and he put them straight, he got them to pull out the stator and check various points, apparantly there are 6 different gear/shaft combinations and there was some mismatching that went on in the factory, on some there are color coded dots on the stator shaft and where it slides in if these colors don't match then it's no good,or if you have one that the dots are the matching colors you still have to make sure they are in alignment, or if you get one with no dots this means that it is a match. Well mine didn't match and within 2 days Kawasaki had the one that matched for me and in my bike no charge. The noise is gone now and I'm back to worry free riding. I can't believe how lucky I was to meet this guy.
